compute condition number when solving triangular systems (bug #43875) * dMatrix.cc (Matrix::solve): Pass true for calc_rcond in calls to utsolve and ltsolve. * CMatrix.cc (ComplexMatrix::solve): Likewise. * fCMatrix.cc (FloatComplexMatrix::solve): Likewise. * fMatrix.cc (FloatMatrix::solve): Likeiwse.
